The Sign of Innocence is a Keyblade that can be wielded by Roxas and Xion in Kingdom Hearts 358/2 Days. It can be upgraded to the Sign of Innocence+. Both of these weapons are Magic-oriented, as shown by their Magic-enhancing abilities.
The Sign of Innocence's handle is white and its smooth, circular, dark indigo guard completely surrounds it. The top of the guard is decorated by three magenta diamonds; one at the base of the blade, and two on either side of this one. The shaft of the blade is rather short and is dark indigo.
The head and teeth of the blade are comprised by a dark indigo cross with a magenta diamond set in three of its four arms, leaving the arm opposite the "teeth" bare. A white ring connects all four arms of the cross. The Keychain token is triangular and resembles the head of the blade, being dark indigo with three magenta triangles and one triangular gap decorating it.
The ground combo starts with an upward slash from the right leg to the left shoulder, followed by the same slash except from the left, and finishes by jumping into the air and performing a spinning slash.
The aerial combo is jumping and into the air turning on a slight angle while doing a spinning slash on the left side and ends with the same spinning slash on the right side.
